To all 111100771/ inlay concern:

'Be it known that I, RICHARD R. WANLEss,

` a citizen of theUnited'Statesand a resident i section.

of the city of New York, borough of Manhattan, in the county an'd Sratejof New York, have invented a new and In] proved Button- Sewing Machine, of which thefollowing is a' full, clear, and exact description. i

This invention relates-to improvements in machines for sewing shank-buttons on garments; and an object is to provide in connec- Lion with such machines a simple device for holding the buttons, the said device being adjnstable to different sizes of buttons.

A further and essential object is to provide a cam movement for shifting the needle-bar in suchmanner as to form extra stitches at the outer side of the shank, somewhat in the manner of hand-sewing, to prevent the drawing out of the thread.

I will describe a button-sewing machine embodying my invention and then point out the novel features in the appendedv claims. l

Reference is to be had tothe accompanying drawings, forming a part of this specification, v

in which similar characters offrejference indicate corresponding parts in all the iigures.

Figure 1 is a `t'ront vievvof` a portion-'Oia sewing-machine arm and illustrating my invention. Fig.2is"a side'elevation, partlyin Fig. 3 isapartial side elevationfand partial section showing the'button-holding device in its uppermost position. Fig. 4 isa section on the line a: of Fig. 2. Fig. 5 is a plan view ofthe cloth-holder and throat-plate employed,and Fig. 6 showsdiagrammatically the manner of sewing and fastening the end of the'thread.

Referring to the drawings, 1 designates the arm of the sewing-machine, on the forward end of which is mounted a rocking frame 2, which carries the needle-bar 3. Rockingmotion is imparted to nthe frame 2 to cause the needle to 4`move to the inner Yportion of abutrounds said bar, engaging at its lower end described.`

bar to release theworlgas will be hereinafter end of which is inclineddownwardiand forf ward, and this lower' end is designed to en in'g on the lower"endl of the i with a collar on thebar and-at its upperend" with a wall of anopening. in the swinging frame.v jAleverQis provided for raisingsaid f f ss? s f seg Y' spring-plate "11, mounted onthe beds-plate of f the machine.

Fig.2.`

Armngeagbeiow ,mangaring-piave 1i is' a bedfplate 18, provided with an opening 19,' j

Lintofwhich j the goods 'I and Tbutton may.` bel .'pre'ssed,v as. indicated, landadjustable. on'ehe .f ,e `"bed-plate ofthel machine is' p1ate'18',`pro`' vided witha slot 2O for the passage of the needle. The plate 1Srb is made adjustable for the purpose of regulating vthe distance between the inner end thereof and the end of the block 10 to provide for vdifferent lengths of button -shanks,\and theupward adjustinent of the jaws 13 and14'is to providefor thediiferent sizes Orcircumference ofbut tons, while the longitudinal adjustment is. to provide for different thicknesses of buttons.

The jaws 13 and 14 are held yieldingly in engagement with a button by means of a spring 21, connected at one end to the jaws roo 1 and at the other end to the block 10. It will be noted that the jaws not only swing toward and from each other, but they are arranged to swing vertically, and as a means for limiting t-he vertical movement or adjusting the `same I provide a set-screw 22, engaging in a lug 23, carried by the jaws, and the head portion of this screw is designed to engage with the upper wall of a notch 24, formed in the block l0.

In operation the garment or the edge thereof is to be placed between the plate 1l and the bed-plate l8,while the block 10 is in its uppermost position, as indicated in Fig. 3, and the button is to be placed upon the goods, as shown in Fig. 2, after which the block l0 is lowered, pressing the plate 1l downward and firmly holding the goods, and the jaws at this time by engaging with the button will hold it securely in place. Then upon the operation of the needle the threads will be carried through the goods within the shank of the button and also at the outer side thereof.

An understanding of the stitching for sewing on the button and for fastening the thread ends may be best understood by reference to Fig. 6. Assuming the needle to rst enter at a, the cam movement will carry the next stitch to b, thence to c, thence to d, thence to e and tof, which makes a tying or fastening for the thread upon a rotation of the cam,and upon another rotation of the cam the stitch will be carried from f to g, thence to 7L, thence to fi, then to j, and out to 7c and Z, forming another fastening to prevent raveling. The movements for fastening the bntton I term the normal movement, while the tyingstitch is the abnormal movement oi. the needle-bar, and during these movements the goods remain stationary.

Having thus described my invention, I claim as new and desire to secure by Letters Patenti l. In a button-sewing machine, a needlebar, means for moving the needle-bar vertically, and means for moving the needle-bar on a horizontal plane to cause a predeter`- mined number of stitches alternately at the inner and outer sides of a button-shank and then to cause a further horizontal movement to form a fastening-stitch while the goods remain stationary, substantially as specified.

2. In a button -sewing machine, a frame mounted to swing on the machine arm, a needle-bar carried in the frame, a cam, and a connection between the cam and frame, the said cam operating the frame to cause a predetermined number of stitches alternately at the inner and outer sides of a button-shank, and then to cause a further swinging movement to form a fastening-stitch adjacent to the rst named stitches, substantially as specied.

3. A machine for sewing on buttons, comprising a needle-bar, a swinging frame in which said needle-bar is mounted, means for causing movements of said swinging frame, a bar movable vertically in the swinging frame, ablock having pivoted connection with said bar, jaws mounted to swing on said block, a screw-rod for moving said jaws toward and from each other and a sprng-yieldin g presserplate operated by said block, substantially as specified.

4. In a machine for sewing on buttons, a needle-bar, means for causing an oscillating movement of the needle-bar, a spring-pressed bar rearward of the needle-bar, a block mounted to swing on said spring-pressed bar, a limiting-screw engaging with the block, jaws mounted on said block to have a vertical swinging movement and to move toward and from each other, and a screw-rod for moving the jaws toward and from each other, substantially as speciedl 5. A machine for sewing on buttons, comprising a needle-bar, means for im parting an oscillating motion to said bar, a block arranged rearward of the needle-bar, buttongripping jaws carried by said block, a springyielding presser-plate adapted to be moved downward and held by the block, and an adjustable plate having an opening for the passage of the machine-needle, substantially as specified. Y

6. A machine for sewingon buttons, comprising a needle-bar, means for imparting an oscillating motion to said needle-bar, a presserblock rearward of the needle-bar and having a downward and forwardly inclined lower end, a presser-plate operated by the block, button-gripping jaws mounted on said block so as to swing vertically and 'toward and from each other, means for adjusting the vertical movement of the jaws, a spring connection between the jaws and the block, and a screw for movingr the jaws toward and from each other, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
